DIGITAL COMPUTER PROGRAMS FOR PLANE MOTIONS WITHIN AND WITHOUT PLANETARY ATMOSPHERES,

Abstract

Programs are discussed for the numerical solution of the exact equations of plane motion of a small vehicle moving in a spherically symmetric gravitational force field and subject to atmospheric forces. The planet is considered fixed and nonrotating, and the atmosphere is regarded as nonrotating and uniformly symmetrical; its density is assumed to have an exponential variation with altitude. A basic program is defined for solutions with constant settings of lift and drag coefficients and there are described two versions of it, the one written for a Bendix G15 computer, the other for an I.B.M. 650 machine. The numerical technique of solution is based on the idea of the instantaneous conic. (Author)
